19 Claims.

One of the objects of this invention is to pro- .vide a generally fiat relatively wide elastic fab-,

of forming a fabric of threads which are shrunk after being woven, by which arrangement I may obtain a more elastic and thinner material than where the threads are shrunk prior to weaving.

f; A further object of the invention is the pro- This invention further consists in the method of forming an elastic fabric which, after being taken from the loom, is in an inelastic state and is rendered elastic by treatment in the finishing process.

with these and other objects in view the invention consists of certain novel features in the construction and method of forming the fabric as will be more fully described and particularly pointed out in the appended claims.

In the accompanying drawing: Y

as corsets or the like, to provide thin material, and

it has been usual in the formation of such material to use elastic and non-elastic threads which will contract upon being taken from the loom in which they are woven under tension, and I have found that by weaving the unshrunk threads, which extend at right angles to and also in the same direction as the elastic threads-and using some sizing in these threads that the fabric will not contract any appreciable extent upon being taken from the loom until they are treated in a manner, to shrink the threads and remove the sizing from .them, whereupon the elastic threads are permitted to contract and every thin fabric is produced which is desired for the purposes above stated the same being either flat or otherwise depending on the arrangement of the elastic threads; and the following is a detailed description of the'present embodiment of this invention illustrating the preferred means by which these advantageous results may be accomplished.

With reference to the drawing, .for the sake of convenience, I will designate one component set of threads 10 as warp threads and the other component set of threads 11 as weft threads, although these threads may be interchanged for convenience or the obtaining of different weaves.

In the weft threads there is provided a pair of yarn or relatively non-elastic threads 12 alternating with a pair of relatively elastic threads 13, each of which may be formed with a rubber or latex core 14 and a covering 15 of a textile material usually of the same material as the non-elastic thread 12. In this manner of positioning the elastic and non-elastic weft threads, the elastic threads are sufliciently close together so that when contraction occurs the fabric will remain substantially flat or in a single plane.

One convenient form of weaving is to cause weft threads to extend alternately-under and over groups 16 and v1'7 of warp threads which I have here illustrated as three threads included in each group, and when in woven condition, as illustrated in Fig. 4. the elastic and non-elastic threads will be related as there shown when taken from the loom. The non-elastic threads 12 as well as warp threads 10 contain a sizing or gum which causes the fabric to be relatively stiff so that when the fabric is removed from the loom with the elastic strands 13 in stretched condition this fabric will not appreciably change but will remain stiff with the rubbers or elastic threads in the stretched condition which they assume in passing through the loom. This invention has to do primarily with silk or rayon threads, although other materials may be used and the gum or sizing is that usually present in the working of this material. It will also be understood that the elastic threads fabric which is woven on a loom substantially forty three inches wide will contract to a width of substantially twenty four inches after being finished and shrunk, although it will be realized this dimension is merely illustrative and not any way confining as to the invention herein disclosed. I

The elastic threads may be of rubber or latex and the non-elastic threads may be twisted to different degrees with their corresponding binding effect as disclosed in the copending application here and above referred to, where a high twist of the relatively'non-elastic threads is disclosed. The fabric thus formed may be used in undergarments and will stretch and snugly fit the body whichis desired in many uses of the same.

The foregoing description is directed solely towards the construction and method illustrated, but I desire it to be understood that I reserve the privilege of resorting to all the changes to which the fabric is susceptible, the invention being defined and limited only by the terms of the appended claims.

I claim:-

1. A method of forming an elastically extendible material, which consists in weaving textile threads having gum or sizing therein with relatively elastic threads of rubber under tension said textile threads being sufiiciently close together and containing sufiicient gum or sizing to provide a substantially non-elastic fabric when taken from the loom, and then degumming the fabric to permit it to contract and be elastically extendible.

2. A method of forming an elastically extendible material, which consists in weaving in the warp textile threads having gum or sizing therein with relatively elastic rubber threads under tension in the weft said textile threads being sufficiently close together and containing suflicient gum or sizing to provide a non-elastic fabric when taken from the loom, and then removing said gum or sizing from the fabric to permit it to contract and be elastically extendible.

3. A method of forming an elastically e'xtendible material which consists in weaving raw silk threads with relatively elastic threads of rubber under tension said silk threads being sufiiciently close together to provide a substantially nonelastic fabric when taken from the loom, and.

4. The method of forming an elastically extendible material, which consists in weaving raw silk threads with rubber threads under tension said silk threads being sufliciently close together to maintain the rubber threads under substantial tension and subsequently removing the gum of the raw silk to finish the fabric so formed.

5. The method of forming a fiat elastic fabric of fine texture, which consists in weaving textile threads having a gum or sizing therein with relatively elastic threads of rubber under tension and spaced in the fabric so as to have an even drawing effect and cause the fabric .to be substantially fiat thus providing a non-elastic fabric when taken from the loom and then removing said gum or sizing to permit it to contract and be elastically extendible and yet be substantially flat.

A method of forming an elastically extendible material, which consists in weaving rubber threads under tension with relatively nonelastic textile threads located sufllciently close together and having a sufficient gum or sizing therein to hold the elastic threads under substantial tension when woven and taken from the loom, and then degumming the fabric to permit a contraction of the rubber threads and provide an elastically extendible fabric.

A method of forming an elastically extendible material which consists in weaving rubber threads under tension with relatively non-elastic textile threads located sufficiently close together and having a suflicient gum or sizing therein to hold the elastic threads under substantial tension when woven and taken from the loom, and then degumming the fabric to permit a contraction of the rubber threads and an elastically extendible fabric, said spacing of the non-elastic threads and amount of gum present being such that a major portion of the contraction in the fabric occurs after the degumming step.

14. An unfinished fabric of woven material comprising relatively non-elastic threads having a gum or sizing therein and relatively elastic threads of rubber stretched under tension with the elastic threads maintained under tension by the spacing of and amount of gum or sizing in the relatively non-elastic threads, said fabric being contractible an amount equal to the major portion of its extendibility in the finished fabric raaaa e upon the removal of said gum or sizing in finishing the fabric 15.
